Well Im looking for an 11.9 ET. Im sure Ill need to build for more and dial down. Recommend me a fuel and air setup! Truck weighs as it sits about 6500lbs. Should be about 6k, or less hopefully, when Im done with it.

S475 over stock lmm on proxies and bmfs got me 12.1.

Had 60k hard miles on the tune, so I figure it had more left in it since the motor never went.

6300lbs also.

My lbz went 11.9 @ 6800 pounds with 45s dual pumps and a 366 and went 11.6 @ 117 on nitrous until it decided to snap motor mounts and bend valves

Guess I should have mention its an 02 lb7. I leaning towards twins because singles seem to be inconsistent. Im thinking S480 over IHI duals and stock sticks. Dont want to spray either because, I know for sure, its inconsistent.

I have a bd staging limiter that doesn't do the trick on a zf buy would be nice for consistent launches on an auto. There's probably a ton of ways to hit a 11.9, are you gonna be bracket racing?

Would like to compete both heads-up SD and bracket SM. So my quickest ET can only be 11.5 but would like to dial 11.9.

Twins are nice but also a PITA
I'll say a decent sized single to keep the engine bay fairly open, easier to work on, not relocating the ps battery, not heating up the oil even more & not kill the rods with torque
Some decent sized injectors & hopefully your cp3 is healthy
